Summary

The determination of mercury in the presence of matrix substances (such as inorganic cations and anions, and organic compounds) was studied by cold vapor atomic absorption spectrometry with „completely continuous micro flow“, using tin(II) chloride in sodium hydroxide solution as reducing reagent. The effects of the diverse substances in the proposed method were found to be much smaller than those in the conventional methods using tin(II) in acid medium or borohydride in alkaline medium as the reducing reagents.
